Abstract: 1,102,788. Sheet delivering in counted batches. HAMILTON TOOL CO. 17 Dec., 1965 [4 March, 1964], No. 53704/65. Heading B6H. Sheet delivering apparatus for delivering of single or multiple printed forms, which may be interleaved with carbon transfer copy sheets comprises a rotary cutting cylinder (22), Fig. 7 (not shown), co-operating with an anvil cylinder (24) to sever a continuous web into sheets A with the aid of knock-down fingers 28, Fig. 1, and the sheets are deposited in an overlapped relationship on to a continuously moving tape conveyer which delivers the sheets into a sheet container 16. The sheets are passed under sheet retarders and depressers 44, 46 the former mounted adjustably on a rod 128 slidably supported on rods 122. The sheets A are delivered to the container 16 in counted batches which are formed by periodic pivotal downward movement of fingers 56 which arrest the leading edge of a foremost sheet allowing following sheets to slide relatively over one another still in overlapped condition, Fig. 2 (not shown), and then lifting the fingers 56 upward to release the batch of sheets which follows the preceding batch spaced from it by a distance (B), Fig. 2 (not shown). Batching is effected by a counter 80, Fig. 7 (not shown), associated with the cutting cylinder (22) and driving a cam (32), whose lobe (84) actuates periodically an electric switch (34) energizing thereby a solenoid (38) of a valve (40) operating a fluid cylinder (23), Fig. 5 (not shown), which rocks an arm (72) associated through shaft (70), link (64) and arm (60) with the fingers 56 which are pivoted downwardly to obturate the movement of the sheets A. Simultaneously, inclined lift rails 90 actuated by cams (92), (94) and interconnected by a link (104) are raised by pivotal displacement of lever (100) to lift off the foremost sheets A the inclination allowing relative further overlapping movement of the following sheets. When the lobe (84) of cam (32) passes the arm (82) of switch (34) cylinder (23) is actuated in the reverse direction to raise the fingers 56 and lifting rails 90 lowered to deposit the batch of sheets on the conveyer the sheets following the preceding batch spaced therefrom by the distance (B). All leading edges of the sheets A are extricated from the fingers 56 by roller brushes 108, adapted to resiliently press the sheets against the conveyer belts 18.

Abstract: 1367336 Pulse radar INTERNATIONAL STANDARD ELECTRIC CORP 25 Nov 1971 [30 Nov 19701 54778/71 Heading H4D A radar surveillance system such as described in Specification 1,340,582 is modified in that signals are provided whenever mobile objects approach the surveyed area. In addition to the threshold circuit CSl n , corresponding to each range interval D n  (Fig. 1, not shown) and used in the system described in the above Specification, another threshold circuit CS2 n  is provided. CS2 n  has wider threshold limits than CS1 n  and produces a signal PAL n  whenever the signal ##, representing the target direction deviation from the aerial axis, indicates that the target is either within a predetermined vicinity of the surveyed area or within the area itself, e.g. within the whole of slice D7a, D7, D7b (Fig. 1, not shown). PAL n  is applied to AND gate P1 n  together with the inverted signal from CS1 n . P1 n  therefore gives a signal when the target is within the surveyed area vicinity, e.g. D7a, D7b, but not when it is within the said area. The signal ## is also applied to device SEC giving a signal D<SP>1</SP> if the sign of ## indicates the object is to the right of the aerial axis, and no signal if to the left. D<SP>1</SP> is applied to AND gates P2 n , P3 n  with the signal from gate P1 n , the D<SP>1</SP> signal to P3 n  being inverted. Signals PAL na  and PAL nb  are therefore provided indicating both the presence of an object in the surveyed area vicinity and also which side of the aerial axis it is on.

Abstract: 1,208,586. Uses of photochromism. TEXAS INSTRUMENTS Inc. 12 Dec 1967 [31 March, 1967], No. 56398/67. Heading C4S. [Also in Divisions G2 and H4] In making a hologram, a coherent signal 2, Fig. 8, is reflected or transmitted by an object 3 to form an information carrying beam 4 which is split, and the partial beams 115, 116, are recombined at the recording medium 5, e.g. a photochromic material. The coherent signal 2 may be obtained from a laser, maser, or a generator of sound waves, X-rays or microwaves. As shown, light from a laser 1 is passed through lens 9 to object 3 and the beam 4 impinges on a beam splitter 111, the partial beam 116 passing directly to the recording medium 5 and the partial beam 115 being concentrated by lens 112, redirected by mirror 113 and passed through a pinhole 114 to form a partial beam 117 which interferes with the partial beam 116 in the medium 5. In modifications, the lens 112 and pinhole 114 are omitted and the beam splitter may be in the form of a Wollaston prism or diffraction grating. Alternatively the medium 5 may itself form the beam splitter with the portion of the beam which passes through it, or is reflected by its front surface being reflected back by at least one external mirror to interfere with the original beam. Such an external mirror may be integral with the recording medium. If the Fourier transform of the object is to be recorded, the information bearing beam is directed through a lens which is a focal length from the recording medium. In the case of objects separated by a barrier from the light source, light pipes may be used to convey light to and from the object. The information carrying beam may be concentrated by means of a concave mirror before being split.

Title: Leak detecting apparatus

Filed: 1972-12-07
Abstract: 1372910 Hydraulic control circuits DRESSER INDUSTRIES Inc 7 Dec 1972 [28 Dec 1971] 56447/72 Heading F1P [Also in Division F2 and G1] In a leak detection circuit for a fuel dispensing system, Fig.1, fuel from a pump 19 passes through a channel 36, Fig.2, located in the pump-head 16, past a spring-loaded check-valve 42 and out through a channel 38 to conduits 14, 12, Fig.1, a valve 28, meter 24 and nozzle 26. When fuel is dispensed accumulators 48, 62 are charged through passages 57, 56 and 64. After the dispensing operation the accumulator 62 remains charged if there is no leak in the system and accumulator 48 discharges at a predetermined rate through a metering passage 60. Thus, a pressure difference on opposite sides of a sliding piston 76 holds the piston in the position shown so that the check-valve 42 can open fully when fuel is dispensed. If there is a leak in the system, fuel flows out from the accumulator 62 faster than it flows out from the accumulator 48. The pressure at the left side of piston 76 is therefore higher and the piston is moved to the right. In this position the valve 42 can only open partially to allow a reduced flow of fuel. This indicates to the operator that a leak is present and the circuit cannot be reset until the leak has been stopped. When this has been effected the piston will be moved back to the position shown after the next leak-free dispensing operation. Accumulator 62 also discharges at a controlled rate so that leaks occuring at a rate which is lower than a predetermined amount do not actuate the circuit.
